Dietary fiber obtained from by-products of food industries acts as a potential functional food ingredient and used in baking, beverages and meat products. Soybean, a rich source of plant protein is a suitable substitute to dairy milk. Processing of soy milk leaves behind large quantities of fiber, which could be incorporated in food formulation as a dietary supplement. With this background high fiber buns were formulated using soy fiber at different levels and analyzed for nutritional quality, physical characteristic and sensory acceptability. Nutritional characteristics of enriched buns were determined using standard methods and results (per 100 g) were: protein, 7.1-7.7 g; fat, 4.8-6.6 g; iron 2.2-3.0 mg and calcium, 74.0-81.0 mg. Phytic acid and tannin were in the range of 19.0-22.8 mg and 47.4-50.1 mg/100g respectively. Bioaccessible Fe ranged from 11.1-23.3 % and Ca from 50.2-95.5 % of total. In vitro digestible protein and starch ranged from 46.8-49.5 and 34.9-68.6 % of total respectively. Addition of fiber influenced the color of the buns as measured by Hunter Lab color meter. Incorporation of soy fiber lowered sensory scores of buns. In conclusion, soy fiber buns were nutritionally superior and can fulfill the consumer requirement of health food.

Ciprofloxacin, CFL is a drug that belongs to the second generation of fluoroquinolone antibiotics with a wide range of effects on Gram-positive and Gram-negative bacteria. The aim of this work was to investigate the interaction of CFL as ligand with divalent biological cations (Mn2+, Ni2+ and Co2+) in approximate physiological conditions. Synthesized complexes were characterized using FTIR and stereo-microscopy. Antimicrobial screening was performed on bacterial strains of Escherichia coli, Salmonella Enteritidis, Enterococcus faecalis and Staphylococcus aureus. The results of FTIR spectroscopy showed that the M(II) complexes with CFL were formed through the oxygen donors of the carboxyl and carbonyl group of the ligand. Stereo-microscopic characterization revealed the difference in color and size of crystals of the ligand and metal complexes. Antimicrobial screening has shown that CFL and complexes have almost similar antimicrobial activity against investigated bacterial strains.

Yttrium belongs to the rare earth elements and critical metals.Yttrium oxide is mostly used in fluoroscent lamps, production ofelectrodes, in electronic filters, lasers, superconductors and asadditives in various titanium-aluminium materials to improve theirproperties. Recovery of yttrium oxide from secondary sourcessuch as red mud, coatings from ceramic industry and phosphors isextremely important. The main aim of this study is to examine theselective recovery of yttrium oxide from Al-Ti based secondarymaterials using one combined method based mostly on leachingfor selective recovery of yttrium containing: crashing and grindingof materials, sieving, leaching of chosen fine fraction withhydrochloric acid, precipitation with oxalic acid in order to producea pure yttrium oxalate, filtration and a final thermal decompositionof yttrium oxalate. The present study summarized mostly theinfluence of different reaction parameters such as leachingtemperature, time and concentration of hydrochloric acid onyttrium dissolution from Al-Ti based secondary materials. Anincrease of dissolution time and temperature increases yttriumdissolution. An increase of pressure from an atmospheric pressureto 0.5 MPa at 150°C leads to the maximum dissolution of yttrium(about 98.6 %). The final produced yttrium oxide after thermaldecomposition of yttrium oxalate was analyzed using SEM andEDS-analysis.

根据应用于反向过程的热力学第一和第二定律，在实现压力平衡的情况下，表达了封闭系统的总最大性能。为了充分解释这两个特征的问题，p-v图中显示了图形风险，其中很明显，灌溉和等温工作中成分的不断膨胀是对环境的灌溉。Na-bazi izvedenog izraza，koristećiodgovarajuće termodinamičke relacije，izveden je izraz zaspecifični maksimalni rad koji je pogodan za analizu。接收到的表达式被视为二维问题，分别作为变量函数：初始压力和初始温度作为比较参数。数学分析的使用证明了最小观测函数的存在，并将其图形输入到空间坐标系中。详细地说，数学分析表明，一般来说，几何函数的函数代表了空间的具体改进。为了更有效地解决和分析问题，将最大雷达函数的复函数观察为具有一个变模态二维的两个函数，通过问题的二维来识别问题。还有一点是，最大功是最小的，并且与零不同。在工作的最后，使用与热力学过程的热力学分析和优化相关的复杂最大网格问题的可能性，以及下一步研究其他气体、半波长气体和范德华气体问题的指南。可以说，分析工作中显示的最大工作模态函数的程序在文献中并不罕见。

By the application of processes of stabilization through drying,separation of seed and grinding of remaining placenta dietaryfiber-rich powdered product was obtained from pepper (Capsicumannum L.) processing waste. Effects of dosing of pepper placentabasedsupplement (1, 2 and 3%) on farinograph, extensographand amylograph parameters, as well as test baking, wereconducted in this study.Addition of pepper placenta-based supplement resulted in anincrease of farinograph water absorption in obtaining of darkerand more intensively colored bread crust and in smaller and moreevenly distributed pores of breadcrumb. It also inhibited thefirming of breadcrumb during bread shelf life. The main negativeeffects of the application of placenta-based supplement were theincrease of dough resistance and the decrease of breadcrumbcohesiveness.

The role of the materials used for packaging is to protect innercontent from external, mostly negative, factors. Besides beingsafe, and with good mechanical properties, these materials needto align with other consumers’ needs and demands, being bothattractive and authentic, while at the same time meetingecological requirements. Gelatin-based thin films are goodcandidates for production of semi-soft cup-shaped products thatcould be used for cruciferous vegetables packaging. These filmswere prepared by a simple solvent evaporation method. Preparedfilms were characterized by swelling study and their mechanicalproperties were investigated. The optical characteristics of thefilms were determined by optical microscopy revealing that thesesystems possess attractive clear and transparent gold-yellowishappearance with a smooth surface.

Silver nanoparticles (AgNPs) were synthesized by “green”, cheap hydrothermal method in an autoclave using sodium citrate and Vascellum pratense polysaccharide extract as reducing and stabilizing agents. Presence of spherical AgNPs was confirmed by UV-VIS spectrophotometry and scanning electron microscopy; particle size was determined as ~ 40 nm. Even though colloidal solution had relatively low absolute value of zeta potential(-15 mV), short term stability studies suggested a stable system, with AgNPs being stabilized by both citrate and fungal polysaccharides, as FTIR spectra confirmed. The colloidal solution showed good antimicrobial activity against both G+/G- bacteria and Candida albicans, including methicilin resistant Staphylococcus aureus (MRSA). Products containing AgNPs and fungal polysaccharides, which possess various biological activities - most important being immunostimulation - may find use in treatment of skin conditions caused by pathogens.
